A fraction of the risk for an even smaller fraction of the reward.
I'm not saying that you should necessarily follow this particular model, but getting out of your social comfort zone, while not easy, can pay big dividends over time.
Also, social media encourages a very performative style of vulnerability: "let me write at length about a small quirk," ignoring the fact that anxiety basically runs their life to such an extent that they need Twitter as a social outlet.
But also, social media creates perfect conditions for such things to become necessary. Some people are especially easy to dehumanize. People say things to me on social media they wouldn't dare say to my face with irritating regularity.
However, their existence reinforces the issues I brought up: it's too easy to cut people out because they said something slightly wrong, they reinforce filter bubbles, and they make it easy to see relationships formed via social media as easily replaced.
Sometimes it is something minor the person just isn't well-versed in. Then the response seems to be proportional to how big their audience is; the bigger the audience the larger the transgression, the "you should really know better".
But then there's also little hints at some more deep-seated issues, things where I'd also find an excuse to leave as soon as possible when I met someone like this in real life. The most common thing I see there is someone considering a group less human because of some arbitrary reason (race, gender, sexual orientation, gender identity), and I don't mean the constant unwilful ignorance fueling microaggressions (I am though one way or another affected by that, they're mostly annoying and rarely uncomfortable enough to end a conversation) but very clear disregard or even disgust for some demographic.
Vulnerability is not required. Communication is stripped of almost all of its context, and is often asynchronous. There is little expectation of any sort of real commitment. People are easily muted, unfollowed, and blocked.
In sanitizing away the messiness of real relationships, we’re left with an empty shell that puts us more in control and yet also more lonely. It would seem that we cannot simply pick and choose which aspects of relationships we want, nor can we relate to others at the scale that social media enables us to.
